The specific embodiment
As shown in Figure 1 and Figure 2, a kind of concrete staircase with lifting seat 11 and connector, comprises step 1 and halfpace 2.
Step 1 consists of side plate 12 and gangboard 13.As shown in Figure 4, gangboard 13 is steel mesh reinforcement concrete structure, and steel mesh reinforcement 17 adopts the less reinforcing bar of diameter to be woven in and forms, and is multistage scalariform.As shown in Figure 3, side plate 12 is steel bar girder concrete structure, and steel bar girder 14 adopts the reinforcing bar that diameter is less to be welded according to the braiding of truss shape.Steel bar girder 14 is vertically welded in steel mesh reinforcement 17 both sides, and both are firmly welded as a whole, then puts into step 1 mould, and concrete perfusion is built and formed step 1.
As shown in Figure 3, Figure 4; in gangboard 13 and side plate 12, be all embedded with the screw nipple 15 of standard module spacing; pre-buried position is provided with the shaped steel 16 that improves intensity and shield, and pre-buried screw nipple 15 and the steel mesh reinforcement 17 in gangboard 13, the steel bar girder 14 in side plate 12 are welded as a whole.The structure that this integrated connection is integrated, high, the whole good stress performance of intensity, shock resistance are strong, and be threaded connection pipe 15 can be convenient, fast, be firmly connected with high-strength bolt with other building unit, solved existing stair and be difficult to the problem being connected with other member, whole stressed property is poor, shock resistance is poor.
As shown in Figure 1, Figure 3, in side plate 12, be also embedded with the lifting seat 11 of lifting and support and connection effect.Lifting seat 11 adopts threaded steel pipe manufacturing, mainly play two aspects: on the one hand, when factory's internal standardization is produced, lifting seat 11 plays a supportive role, stair are not contacted with ground, between stair and stair, can neatly put by lifting seat 11 laminations, use with lifting seat 11 support bars that match and be connected to each other, the normal space between keeping every layer and firmly connecting; On the other hand, in building construction process, use is pretended in 11 liftings of lifting seat, can rapidly stair be hung on to highrise building, more convenient, fast with high-strength bolt, firm and other building unit is assembled.
As shown in Figure 5, halfpace 2 by panel 21 and be positioned at its bottom be used for strengthen stupefied 22 of intensity and form.Panel 21 is steel mesh reinforcement concrete structure, and steel mesh reinforcement 17 is adopted reinforcing bar that diameter is less and is woven in and forms.Stupefied 22 is steel bar girder 14 concrete structures, and steel bar girder 14 adopts the reinforcing bar that diameter is less to be welded according to the braiding of truss shape.Steel mesh reinforcement 17 in panel 21 is welded as a whole with the steel bar girder 14 in stupefied 22, then puts into halfpace 2 moulds, and concrete perfusion is built and formed halfpace 2.
Halfpace 2 is also embedded with the screw nipple 15 of standard module spacing; described pre-buried position is provided with the shaped steel 16 that improves intensity and shield; steel bar girder 14 in steel mesh reinforcement 17, stupefied 22 in screw nipple 15 and panel 21 is welded as a whole; high, the whole good stress performance of intensity, shock resistance are strong, and be threaded connection pipe 15 can be convenient, fast, be firmly connected with high-strength bolt with step 1 or other building unit.In halfpace 2, be also embedded with the lifting seat 11 of lifting and support and connection effect.
Above step 1 and halfpace 2 connect into whole band lifting seat 11 and the concrete staircase of connector fast by high-strength bolt, described concrete staircase top is provided with handrail by bolted mode, described concrete staircase bottom is provided with cleat stanchion 3 by bolted mode, and described step 1, halfpace 2, cleat stanchion 3 and handrail adopt high-strength bolt to be connected each other.With bolts, in Construction of High-rise, than welding or concreting, do not need welding machine and concrete conveyance, speed is faster, more convenient.
Except above embodiment, screw nipple 15 of the present utility model also can substitute with nut or other connectors, other modes such as welding or bolt connect also can be with bundle, be spirally connected, snapping, riveted joint substitute, and the stupefied 22 of reinforcement intensity also can not established in halfpace 2 bottoms, etc.Above embodiment is to explanation of the present utility model, and non-limiting, and more than just part is given an example.Should be noted that, concerning the technician of the industry, simple transformation and the improvement according to basic principle of the present utility model and structure, carried out, the combination of carrying out according to above embodiment, includes within protection domain of the present utility model.
